  2. Gas networks simulation - Wikipedia

    en.wikipedia.org/wiki/Gas_networks_simulation

    Gas networks simulation or gas pipeline simulation is a process of defining the mathematical model of gas transmission and gas distribution systems, which are usually composed of highly integrated pipe networks operating over a wide range of pressures. Simulation allows to predict the behaviour of gas network systems under different conditions ...

  3. Chromium(VI) oxide peroxide - Wikipedia

    en.wikipedia.org/wiki/Chromium(VI)_oxide_peroxide

    The structure of the pyridine complex has been determined crystallographically. [2] Adducts with other N-heterocycles have also been characterized similarly. [3] Aqueous chromium(VI) oxide peroxide decomposes in a few seconds, turning green as chromium(III) compounds are formed. [4] 2 CrO(O 2) 2 + 7 H 2 O 2 + 6 H + → 2 Cr 3+ + 10 H 2 O + 7 O 2

  4. Pentafluoroethane - Wikipedia

    en.wikipedia.org/wiki/Pentafluoroethane

    Shipping container for the gas, shown in Japan. Pentafluoroethane in a near azeotropic mixture with difluoromethane is known as R-410A, a common replacement for various chlorofluorocarbons (commonly known as Freon) in new refrigerant systems.

    [77] [79] A decisive step further was the transition of the model to 2+1D, [81] where a number of different structures were obtained, referred to by the authors as “vicinal creatures”—step bunches, step meanders, nano-pillars, nanowires, etc. [81] The vicCA model was extensively used by Alexey Redkov [82] to develop a Machine Learning ...

    HCFC-123 is used in large tonnage centrifugal chiller applications, and is the most efficient refrigerant currently in use in the marketplace for HVAC applications. HCFC-123 is also used as a testing agent for bypass leakage of carbon adsorbers in gas filtration systems, and as the primary chemical in Halotron I fire-extinguishing agent. [2]

  7. Open energy system models - Wikipedia

    en.wikipedia.org/wiki/Open_energy_system_models

    The Global Energy System Model (GENeSYS‑MOD) is a linear cost-minimizing optimization model being developed at Technische Universität Berlin, Germany. [f] The project was originally based on the OSeMOSYS framework and the first version was released in 2017 using GAMS. [143] The codebase was later translated into Julia. Both versions and a ...

  8. Membrane gas separation - Wikipedia

    en.wikipedia.org/wiki/Membrane_gas_separation

    This model is employed when the pores in the polymer membrane appear and disappear faster relative to the movement of the particles. [5] In a typical membrane system the incoming feed stream is separated into two components: permeant and retentate. Permeant is the gas that travels across the membrane and the retentate is what is left of the feed.

  9. Analogical models - Wikipedia

    en.wikipedia.org/wiki/Analogical_models

    The Mechanism of the Analogue Model. [5]Many different instruments and systems can be used to create an analogical model. [6]"Many important discoveries have been made when scientists commenced their work as if their theoretically postulated models of atoms, viruses, vitamins, hormones, and genes had actual, real world substantial existence.
